"No, Mr Gerard, you go on, and leave me to follow you slowly," answered Fleming. "If I stop, you'll easily find me again." We, of course, were ready enough to follow this advice; so Jerry, Surley, and I, pushed on up the mountain as fast as we could climb towards the nearest herd of guanacoes. They were of a light-brown colour, of about the size of a stag. I should describe the animals we saw as having small heads, with large and brilliant eyes, thick lips, and ears long and movable. The neck was very long, and kept perfectly upright, while the haunches were slightly elevated; so that they looked somewhat like little camels--the purpose of which, indeed, they serve when domesticated. We could see several herds in different parts on the side of the mountain. There was one low down near the path in the direction the doctor and his companions had taken. They were feeding quietly, when one looked up, then another, and away the whole herd scampered at a tremendous rate up the mountain. We thought that the sight of the doctor's party had put them to flight; and it showed us that we must be cautious in approaching the herd we had marked. Old Surley was very eager to be after them, and we had great difficulty in keeping him back. The air was keen and at the same time hot. There was not a cloud in the intense blue sky, and the rays of the sun came down with great force, and blistered our skin and peeled our noses till we were afraid of touching them; but we did not think much about that trifle while the guanacoes were in sight. Concealing ourselves as much as possible behind rocks and bushes, and here and there an evergreen quillay-tree, we got nearer and nearer to them. Sometimes we got behind clumps of the great chandelier-like cactus, whose sturdy green twisted stems afforded us capital shelter. "It is lucky we are not very big, or we should not be able to hide ourselves so well," observed Jerry as we crept on. The valley lay far below us, with steep precipices and a brawling torrent, with rocks and shrubs scattered about; and high above us wild jagged peaks and snow-covered mountain-tops. The stillness of the air was most extraordinary. Not a sound reached our ears. Never have I been in a wilder or more magnificent scene. I do not know what our four-footed companion thought of it, but he certainly enjoyed the idea of catching a guanaco--so did we, indeed, more than anything else. We had got within five hundred yards of the nearest without being discovered. Hitherto we had gone on very cautiously. Our eagerness overcame our discretion. We left cover and ran on exposing ourselves to view.
